TROUBLESHOOTING
Check incoming power. Confirm ON/OFF switch is flipped to the "on" position.
Check power supply line.
Check the position of the conveyor speed control knob.
Check the voltage to the DC drive board. The incoming voltage should be equal to
the line voltage.
Check the voltage from DC drive board. The voltage is DC and will vary with the
speed setting. If there is no output voltage, replace the board, 203-62.
Check the wiring to the motor. Replace the gear motor.
Check the position of the conveyor temperature control knob.
Check the voltage to the voltage controller. The incoming voltage will vary with
the speed setting.
Check heat element for continuity. The 220V element has a resistance of 97 ohms.
NOTE: The resistance given is a nominal value.
